Idk why it kept logging me out -.-
Anyways...Lol xD You just forgot to do a few things. But at least you got the parenthesis and the slashes right; most people forget to do those.
Here's an example:
\''(\cal\Large\color{cyan}{Hi~Mipie~:D!!}\)
If you take away the two (``) at the beginning, it will turn out like:
\(\cal\Large\color{cyan}{Hi~Mipie~:D!!}\)
